During the 15-year period from 1999 to 2015, there were 273 cases that
matched the initial CPT search, but only 142 met inclusion criteria for this study.
Demographics of our study are shown in Table 1, demonstrating that of the
orbital lesions investigated, 57% were found in females, and 75% of all the
lesions were found in Caucasian patients. Inferotempral 1 2.0%
they lacked histopathological biopsy and if the lesion was limited to the eyelids
or eyeball without orbital involvement. The number and percentage of each
subtype of neoplastic and non-neoplastic disease was calculated.
The number and percentage of lesions in each major category are shown
in Table 2. The most common type of orbital lesions presenting in Arkansas
were cystic lesions, accounting for 25.4%, followed by inflammatory lesions
(13.4%) and lacrimal gland lesions (13.4%).
The demographics and orbital mass breakdown by age group are shown
in Tables 3,4,5 and 6. Amongst pediatric patients less than the 18 years, the
most common orbital lesion was a dermoid cyst, accounting for 55.1% of all
masses within this age group. Orbital lesions occurred more frequently in Cau-
casians (80%) and in males (53%) within the 0-18 age group. The most com-
mon orbital location in this age group was the superotemporal region.
In the 19-to-39-year-old age group (Table 4), the most common orbital
lesions were the dermolipoma (8.3%) hemangiopericytoma (8.3%) and or-
bital abscesses (8.3%). Orbital lesion occurred more frequently in Caucasians

(62.5%) and in females (70.8%). The most common orbital location in this age
group was the lacrimal gland.
In the 40-to-64-year-old age group (Table 5), there was not one over-
all common lesion. Orbital lesion tended to occur slightly more frequently in
females (56.8%) and in Caucasians (68.2%). The lacrimal gland and supero-
temporal region of the orbit were the most common location for orbital lesions
in this age group.
In the 65-plus age group (Table 6), the most common orbital lesion was
a squamous cell carcinoma making up 16% of lesions. Orbital lesion occurred
more frequently in Caucasians (88%) and in females (64%). The lacrimal gland
and temporal region of the orbit were the most common location for orbital
lesions in the 65-plus age group.
Discussion
The authors included all orbital tumors and simulating masses seen at
two tertiary institutes in Arkansas over the last 15 years with histopathologi-
